In recent years, with the rapid development of urbanization and the frequent use of air conditioning engineering, the application of geothermal energy has become increasingly extensive. Geothermal energy is a renewable energy source, which can reduce the burning of fossil fuels, reduce air pollution and achieve sustainable development. Ground source heat pump has become an important heat source of heating in northern cities. Therefore, it is especially important to discuss the several shortcomings of the geothermal source heat pump unit.
First of all, the limitation of the high cost of ground source heat pump system. The construction cost of the geothermal source heat pump system is usually high. In particular, the installation of the underground heat collector is not only time consuming but also requires a large amount of construction materials such as drilling rig, gratings and tubes. Its high construction cost and high cost of follow-up maintenance put a lot of pressure on families.
Second, the ground source heat pump system has high requirements for the geography of the surrounding environment. Geothermal energy sources need to be deep underground where the temperature is relatively stable. Therefore, this type of system needs to be specifically tailored for the specific geographical environment. For ground source heat pump systems that are installed in areas such as plateaus and mountains, the system becomes more difficult to construct since altitude has a direct impact on the temperature of the environment. Furthermore, due to the different geothermal conditions of different regions, the same configuration of the ground source heat pump system is not suitable for different regions, which makes the selection of the specific model determined by the regional environment factors and limits its application.
Whats more, the use and maintenance of ground source heat pump system requires a certain amount of knowledge and experience, and improper use and maintenance may cause serious problems in engineering. For example, regular maintenance is essential to the efficient operation of the geothermal source heat pump unit, including refrigerant and system filters, but due to the lack of experience, improper maintenance of the system can lead to the collapse of the unit.
Finally, the ground source heat pump system has certain requirements for the indoor environment. Because these types of heat pumps depend on fans to circulate the cooled and heated air, the indoor environment must be well ventilated. The indoor environment should be kept as airtight as possible and without clutter in order to ensure good air circulation. If there is too much clutter or the ventilation is not good, it will affect the cooling or heating efficiency of the system.
In conclusion, despite its many advantages, the current ground source heat pump unit still has several shortcomings such as its high cost, geographical limitations and quality assurance requirements, which need to be further improved and developed. However, thanks to the better utilization of geothermal energy and the development of ground source heat pump technology, these problems can be further resolved.
